Ecowatt Drive K320 series Communication
®
First, set the serial port to COM1. Then, set the baud rate consistently with P14.01. The data bits,
check bits, and end bits must be set consistently with P14.02. If the RTU mode is selected, you
need to select the hexadecimal form Input HEX. To set the software to automatically execute
the CRC function, you need to select ModbusRTU, select CRC16 (MODBU SRTU), and set the
start byte to 1. After the auto CRC check function is enabled, do not enter CRC information in
commands. Otherwise, command errors may occur due to repeated CRC check.
The commissioning command to set the VFD whose address is 03H to be forward running is
as follows:
